python3帮助类，用于插件开发和nagios管理。
python-nagios-helpers3的Python项目详细描述
python nagios helpers a.k.anaghelp是用于构建nagiosactive插件的类集合。 强烈建议使用python-textops 操作收集的数据。
下面是一个活动python插件的示例，创建一个文件linux_fsfull.py:
from naghelp import *
from textops import *
class LinuxFsFull(ActivePlugin):
""" Basic plugin to monitor full filesystems on Linux systems"""
cmd_params = 'user,passwd'
tcp_ports = '22'
def collect_data(self,data):
data.df = Ssh(self.host.ip,self.host.user,self.host.passwd).run('df -h')
def parse_data(self,data):
df = data.df.skip(1)
data.fs_critical = df.greaterequal(98,key=cuts(r'(\d+)%')).cut(col='5,4').renderitems()
data.fs_warning = df.inrange(95,98,key=cuts(r'(\d+)%')).cut(col='5,4').renderitems()
data.fs_ok = df.lessthan(95,key=cuts(r'(\d+)%')).cut(col='5,4').renderitems()
def build_response(self,data):
self.response.add_list(CRITICAL,data.fs_critical)
self.response.add_list(WARNING,data.fs_warning)
self.response.add_list(OK,data.fs_ok)
if __name__ == '__main__':
LinuxFsFull().run()
手动执行：
python linux_fsfull.py --ip=127.0.0.1 --user=naghelp --passwd=lgpl
如果出错，它可能会返回如下信息：
STATUS : CRITICAL:2, WARNING:1, OK:3 ==================================[ STATUS ]================================== ----( CRITICAL )---------------------------------------------------------------- / : 98% /home : 99% ----( WARNING )----------------------------------------------------------------- /run/shm : 95% ----( OK )---------------------------------------------------------------------- /dev : 1% /run : 1% /run/lock : 0% ============================[ Plugin Informations ]============================= Plugin name : __main__.LinuxFsFull Description : Basic plugin to monitor full filesystems on Linux systems Ports used : tcp = 22, udp = none Execution time : 0:00:00.673851 Exit code : 2 (CRITICAL), __sublevel__=0
或者如果没有错误：
OK ============================[ Plugin Informations ]============================= Plugin name : __main__.LinuxFsFull Description : Basic plugin to monitor full filesystems on Linux systems Ports used : tcp = 22, udp = none Execution time : 0:00:00.845603 Exit code : 0 (OK), __sublevel__=0
naghelp将自动管理一些选项：
$ python linux_fsfull.py -h
Usage:
linux_fsfull.py [options]
Options:
-h, --help show this help message and exit
-v Verbose : display informational messages
-d Debug : display debug messages
-l FILE Redirect logs into a file
-i Display plugin description
-n Must be used when the plugin is started by nagios
-s Save collected data in a temporary file
-r Use saved collected data (option -s)
-a Collect data only and print them
-b Collect and parse data only and print them
Host attributes:
To be used to force host attributes values
--passwd=PASSWD Passwd
--ip=IP Host IP address
--user=USER User
--name=NAME Hostname
